How do I solve this?
Oliga [24]

Answer:

The heat contained is 1236 Joules

Explanation:

As we know

Q = mc\DeltaT

Where

\DeltaT is the change in temperature

m is the mass in grams

c is the specific heat of water (ice) = 2.06 joules/gram

Substituting the given values, we get -

Q = 20 * (-15+45)*2.06\\Q = 20*2.06*30\\Q = 1236Joules

State three reasons why an airborne pollutant might be deposited close to its source
den301095 [7]

Explanation:

Air borne pollutants are usually very light particles that are usually carried in the air in the atmosphere. Some of these pollutants can be carried far away and some are found close to their sources.

Some of the factors are:

  • Wind pressure: if wind pressure is low, pollutants will not be carried far away. In this situation, the particles will be blown and carried over a short distance from their sources. When wind pressure is very high, pollutants will be carried extensively into farther areas.
  • Pollutants can be trapped in snow. In a snowy area, when pollutants reach sky high and enters condensed water in the atmosphere, they can become super cooled into ice and fall back within the same area where they are formed.
  • Rain water can also cause pollutants to be dispersed within a short area. Pollutants can mix with rain water and carrier back to the area where they were originally formed.
